Law launched the proceedings after obtaining a court order disclosing police documents on his case, which found his voicemail messages had been targeted by Mulcaire.

His lawyer Graham Shear, who is not representing Law in the News of the World proceedings, is also suing the paper.

Shear told The Independent

The police came to see me and alerted me that I was the subject of, or appeared to be the subject of, phone hacking relating to a client or clients during 2004 and 2005.

We are currently awaiting additional disclosure from the police and from News Group and cross-referencing with other victims of phone hacking.

The paper also reports that 22 lawyers acting for claimants in the phone-hacking case will meet today to ‘draw up their collective strategy in taking News Group [the News of the World’s parent company] to court”, and to decide which five test cases will go before the judge hearing the case, Mr Justice Vos.

Former MP George Galloway told the Independent he has been shown evidence that Mulcaire had his mobile number and voicemail pin-number – and that the page is ‘marked with the first name of a former News of the World journalist who has not previously been arrested by the current inquiry team”.
